How to get read data from response header in jquery/javascript [duplicate]

Answer 1

In JavaScript, using XMLHttpRequest you can do that using getAllResponseHeaders() method.

jQuery also allowing to call that method. See more.

Answer 2

Both XMLHttpRequest and jqXHR (which is the object jQuery wraps around AJAX requests) have a getResponseHeader() method, so in the always() handler (jQuery) or readyState handler (XMLHttpRequest), do this.getResponseHeader('Location').

Bear in mind that if your server also sends a redirect status code (301/ 302) that redirect will be automatically followed, and there's no way to access the intermediate-headers returned.
